6  PROBLEMS ADDRESSED IN VMS721_DQCONFIG-V0100 KIT


      o  On systems that include IDE/ATA or ATAPI  drives,  when  booted
         from  one  of  these devices, a second unit on the same IDE bus
         would not autoconfigure.  For example, if system boot  is  from
         DQA0:,   drive   DQA1:    would  not  be  auto-configured,  and
         vice-versa.   Currently  the  only  systems  affected  are  the
         DS10/VS10/XP90.

         Images Affected:

          -  [SYS$LDR]SYS$ICBM.EXE


      o  ES40 machines crash when a KZPAC is installed in Hose 0 and  an
         attempt  is made to mount a CD-ROM.  This problem is also seen,
         to a lesser degree, on other platforms.

         Images Affected:

          -  [SYS$LDR]SYS$DQDRIVER.EXE


      o  Remove DMA support on the following platforms:

          o  DPWS-xxxau

          o  XP1000

     This kit requires a system reboot.  Compaq strongly recommends that
     a  reboot  is performed immediately after kit installation to avoid
     system instability

     If you have other nodes in your OpenVMS cluster, they must also  be
     rebooted  in  order  to make use of the new image(s).  If it is not
     possible or convenient to reboot the entire cluster at this time, a
     rolling re-boot may be performed.
